You know that bit in The Prince of Egypt when Moses encounters Miriam and Aaron as an adult and Miriam quietly reprises the lullaby portion of “Deliver Us” a cappella, and it’s haunting and impactful in its simplicity?
That’s the vibe Wangji singing Wangxian.mp3 in the cave SHOULD have had, but unfortunately CQL is allergic to ever having the song be diegetic!
However, right now (and also Frequently) I would say...
Wuxian Wei is Cool Middle Schooler from late 1990s California who, like many kids in 1990s California, Does Martial Arts. Unlike most of them, however, his teacher is a Chinese national who flies him out to Wuhan for ten weeks every summer (and may or may not be some kind of gangster? who wears that much purple? who does kung fu in a suit outside the movies?? is it legal to own that many swords? anyway).
It is not for Wuxian to question how Jiang-shifu manages to own a large manor house on multiple acres of waterfront in the middle of a densely-occupied city while not apparently working. Or why all the locals call him "Jiang-jiujiu" (even the really old ones??). Or who that really sick looking guy is who had the real sword that Shifu has now given to him and told him he has to carry all the time -- swords aren't allowed at school, Shifu!!!
Anyway Wuxian is pretty normal, he thinks. Just a guy with a sport. His biggest worry at the moment is his role in the school play, and how he's going to make it to rehearsals when he also has band and orchestra to work on.
Meanwhile, far away, an ancient weapon is stirring from where it was entombed for fourteen-hundred years... and the dead are rising.
